Chosen Solution
When I turn on the computer, the keyboard starts blinking about every 2 or 3 seconds. The screen never lights up. I can turn it off by holding on/off button for 15 or so seconds. But every time I turn it on same thing happens.
I have had this same model come into my shop with this same issue. I replaced the BIOS chip. No change. I was able to get it to boot for a second by removing the CMOS battery but It blue screened almost immediately. These boards are terrible. So in short, Yes your motherboard has failed.
My wife also has this problem with a Surface Laptop. The only solution that I have come up with is holding the power button until the device powers off (abt. 10 seconds) and then turning it back on. I’m not certain this is the cause, but my wife hardly ever “shuts down” windows. She just prefers to close the lid, which may cause the computer to do a variety of things. All of those settings are available in the power settings menu under “Change what happens when I close the lid…”
